Localization

Using Intl

Documentation

DevExtreme widgets can be localized by means of the Intl object. You need to link the devextreme-intl module, and DevExtreme dictionaries for desired locales (see the <head> tag of index.html). Using Angular, Vue and React, get all the needed components as imported modules instead (see app.component.ts, App.vue and App.js correspondingly). Then, set the current locale with the DevExpress.localization.locale method.
